This uses RE2 to implement a case-insensitive substring search. Originally, I implemented this using utf8proc, but then found it was about an order of magnitude slower than RE2. (This isn't an apples-to-apples comparison; utf8proc does it more 'properly' and handles more Unicode corners.) So I switched to just doing it with RE2 instead, especially since the utf8proc approach was complicated. (You can still see it in the original commit here if you're curious.) -- This is an automated message from the Apache Git Service.
